A 37-year soil experiment revealed a hidden climate threat
A 37-year soil warming experiment in Harvard Forest has revealed that stable carbon stores in soil begin to decompose as temperatures rise, releasing more CO2 than previously anticipated. This finding suggests that forest soils may become a larger contributor to atmospheric carbon as global temperatures increase.
After nearly 40 years of research, scientists have uncovered evidence that challenges a long held assumption about forest soils. The world's longest running soil warming experiment suggests that even carbon once considered stable can begin to break down as temperatures rise, releasing additional CO 2 into the atmosphere.
